just got a new atx case from aspire with back-lite blue glow and thermometer. after installation all audio was lost. id hear a suddle ring when sound should be coming out but thats it. i install everything back in the origional case and audio returns. the case did not come with a power supply but can be sold with a 420 power upply. i have a 280. could an insufficient power supply explaine this loss of audio?
thanks!!
